Adding style in $refs?

javascript vue.js

You're not supposed to use cssText but instead use the JavaScript API to set styles (which you can do on $refs, too):

let $ref = this.$refs['ticketCode_' + this.resoTrans_id]$ref.style.backgroundColor = '#66bb6a';$ref.style.border = '1px solid #66bb6a';...

Even better is to utilize Vue's power for that directly in your template:

<your-element ref="'ticketCode_' + resoTrans_id" :style="{ backgroundColor: '#66bb6a', border: '1px solid #66bb6a' /* ... */ }" />

javascript vue.js

apply directly $refs.objectkey style

this.$refs['ticketCode_' + this.resoTrans_id].style.background="red"
